Question about climate change

CO2 is at it's lowest level now due to the 2.5 million year ice age that we are in. It came close to disaster level for plants.

 

400 ppm is less than 280 ppm? Where do you get this stuff?

As plants were thriving at 280 ppm, claiming that plants were CO2-starved is delusional.

 

280 ppm is close to the 150 ppm plants need to survive. We are at an historical low, even at 400 ppm in earths history.

 

The snowball earth period is more like 500 million years ago. Talking about 50 million years ago is not relevant to the question asked.

You can't claim warming caused the oceans to burp CO2 on snowball earth, because the oceans were frozen. And again, hundreds of Milankovitch cycles went by with not a thing happening, so any "a little warming causes an ice albedo feedback" theory is also wrong. Your theory is contradicted by the data, so your theory is wrong. AGW theory explains observed reality perfectly, so it is the accepted theory.

 

So why then do corn yields here drop when the corn is exposed to very high temps? Reality isn't kind to your theories.

In Canada and Russia. But very little, because you can't crow crops on bedrock and muskeg. The tropics are screwed hard.

or shorter, due to the heat.

Higher specific humidity, lower relative humidity, so more evaporation and dryer soil

Not sensible, as that's a one shot thing. One a glacier melts, it's gone. What will happen is more precipitation falling as rain and running off immediately, leaving less water available when needed.

 

That’s too funny. Is that all you’ve got ??

Very high temperatures ??

No crops on bedrock ??

Lower RH ??

When the glaciers all melt ??

Wow.

 

The point about plants and CO2 is complete nonsense because the world is not a controlled laboratory.

The important thing to note is what happens with CO2 ppm at more than 400. The NAS asked that and addressed it in their report on climate change. BEST was set up by skeptics as an independent study and so far has come up with similar conclusions as the mainstream.

 

The average CO2 concentration of the earth is ~ 2500 ppm. Nothing bad happened and many good things resulted from this abundance of CO2.

Plants thrive on higher CO2 concentrations.

 

Whcih part of it did you disagree with?

You're saying warming doesn't cause higher temperatures? Fascinating.

You're denying that northern Canada is mostly exposed bedrock or muskeg, and that neither of those is soil?

You're denying the amount of water vapor that can be held by air increases exponentially with temperature?

You're denying that increasing temperatures will melt glaciers?

Indeed. As you seem completely detached from reality, there's little point in talking to you.

 

The reality is that global warming is beneficial. You’ve provided nothing to disprove that and still refuse to do the necessary homework.

 

Ha ha funny. Just because it gets hotter in one place and increases a crop yield, you think it’s advantageous ? Well, England is producing wine at a higher rate in higher elevations. I’m sure Floridians think that’s a good trade off when they lose their freshwater supply from our increasing salt water tides encroaching on the Everglades. They can just order England’s wine.

The displacement of populations in lower areas is causing a huge problem. Maybe you haven’t noticed the migration from Central America...And, it’s actually getting colder winters in some areas due to a warnmer Arctic.

These ‘ Warner is better” sound like Fix News anecdotes. It’s the rate of change. If it happens slowly, which it isn’t, we can adapt more easily. Maybe we can grow gills over time. Otherwise, it’s a huge expensive prinkem.

 

Warmer is beneficial. That’s very clear. Increased crop yields, increased growing seasons, increased arable land, and increased water available for irrigation are examples of that.

The illegal immigration from Central America has absolutely nothing to do with global warming.

There is nothing uniquely fast about the current rate of warming. Five of the previous warm periods in the current interglacial have warmed at a higher rate.

Are you AOC ??

 

Nothing bad happened to humans because there were no humans then. Ice core data shows that for several hundred thousand years, it's been 300 or less. It's now 400+.

Scientists are trying to figure out the effect of CO2 ppm that high on human beings. NAS and multiple science organizations believe that if it is too high, then surface temp. anomaly plus ocean heat content will rise considerably. BEST, which was supported by skeptics, have reached a similar conclusion.

The last point is ridiculous because the planet is not a laboratory.

 

Where do you get this BS ??

Nothing bad happened to the earth when CO2 was 8000 ppm. We didn’t turn into Venus.

What is the effect of CO2 on humans ?? Humans can withstand 50,000 ppm with no ill effects.

When CO2 levels were 8000 ppm in the Cambrian Period global average temperature was ~ 8 deg C higher than today. The earth did fine. Using the IPCC A1B CO2 scenario and using the data supported climate sensitivity of ~ 1 deg C shows a total temperature gain of 1 deg C per century. That’s nothing to worry about.

You don’t believe that increases in both temperature and CO2 increases plant growth ?? That’s ridiculous.

 

"The illegal immigration from Central America has absolutely nothing to do with global warming" -

but has everything to do with the global poverty that MAGA ("America First") will only exacerbate.

- and regardless of the reality of global warming, relentless burning of fossil fuels is environmentally unsustainable, which is why China and the EU are moving toward electric vehicles.

Speaking of AOC, this article exposes the dangers of the ignorant self-interestedness of the Right (we are all self-interested, but the Right takes self-interestedness to very dark places..

https://qz.com/1583500/trump-rally-aoc-sucks-chant-is-a-dangerous-maga-provocation/

<<<Trump rally’s “AOC sucks” chant is the latest dangerous MAGA provocation
The real-world effect:
"Prosecutions for death threats against US politicians spiked in 2018, as Quartz recently wrote. In general, about 75% of those charged for making threats against US politicians have come from the ideological right, based on analysis of cases going back to 1990 by the Prosecution Project. They are almost entirely US citizens, male, and roughly 85% white, and their targets are mostly Democrats.">>>

Here is a solution to the self-interested ignorance, fear and hatred emanating from the Right: it does not require the higher taxes their selfish asses are so vehemently opposed to.

China is only interested in world domination. They develop and sell technologies that result in economic harm to the western democracies. To believe that China is concerned about global warming is absurd. German and Danish citizens pay triple what we pay in the US for electricity thanks to their commitment to green energy.

AOC is a moron.

 

Link???

What am I doing? There is never a link

 

There was no industrial civilization then with seven billion people dependent on the same.

BS, my foot. Your lack of common sense is incredible.

 

Where do you get yours?

 

What I think happens, because you get some gob smackingly wrong is that they hear something from someone like o’reilly and they do not bother to fact check but they remember it and over time it becomes misremembered more and more which is why we are getting these hilarious claims at the moment

 

We produce more co2 than the plants can absorb for the last two hundred + years. So far the rocks and ocean has absorbed this co2 which has significantly slowed the rise of co2 levels in the air. Due to the complex way they interact even if we stop producing co2 today it will still rise for hundreds of years to come. We are not going to remove co2 from the air mechanically and projects that do that are insulting jokes aimed at stupid people that fund things like solar roadways.

We do need to do something about our co2 emissions.
It needs to be global.
The green deal is an appalling joke.
Planet is going to change and we to adapt with it.
Neither party has a plan
Nuclear is part of the solution, renewables, energy storage (Not Li-ION) and biofuels possibly algae but not definitely
Maybe OTEC can be made viable this would solve everything

Also legalise weed and then ban growing it under lighting commercially (So only home users can use lights) it's insulting people are growing cannabis under HPS lighting with air con in California use a bloody greenhouse even if you supplement the lighting.

They do this in the UK to grow tomatoes profitably! There is no excuse.

Farming should also be decentralised too much reliance on "mega" farms and shipping food 1000's km which is poor food security long term and literally exporting water.

 

China seeking world domination?

That's a perfect example of the kettle calling the pot black!.... a couple of months back I heard (on the radio) some-one from the current US administration saying:" If we can keep them at bay for another couple of years, they (China) will never catch up..."

Best solution to competing empires: signing up to an international rules-based system.

[We almost achieved that in 1946, when the image of a mushroom-shaped cloud over Hiroshima was still etched into people's brains; some of the delegates present at the creation of the UN charter grasped the need for a UNSC minus possession of veto power by the permanent members of the SC...]

Back to "global warming":

Been to Beijing or Bombay recently? On some days, breathing the air is a scary experience!
China is of necessity, possibly more concerned about non-CO2 pollution resulting from burning fossil fuels.

Yes - many countries trying to do something about "global warming" (whether misguided or not) are paying a higher price for electricity.

Solution: power the world's electrical grids via solar panels covering the world's deserts: result: free global electricity, and a corresponding increase in global wealth. Funded by an IMF authorised to print the funds for that specific purpose. No Inflation (because the materials, know how and labour are all available, without competing with current private sector resource consumption )

As for AOC, she is an inspirational and capable orator.eg, "this job (ie of politicians) is not supposed to be a comfortable (sit-in) for one's entire life".

Do your homework. It is very easy to look this up.

 

So what ??

Your willingness to shut down civilization because of some computer models which don't match reality is hardly an illustration of common sense. The Chinese know better and are using the idiocy of the global warming alarmists to further their plans for world domination.

 

Keep going. The earth is over 4 billion years old.
